利用表达式求解和栈的只是,设计一个简易的数学题库, 可供小学生作业,并能给出分数。
要求:建立试题库文件,随机产生 n 个题目;题目涉及加减乘除,带括弧的混合运算;随时可以退出;保留历史分数,能回顾历史,给出与历史分数比较后的评价。(Use solving expressions and stack just design a simple math exam, students for the job, and can give a score.
Requirements: Create test file, randomly generating n topics topics involving addition, subtraction with parentheses mixing operation ready to quit keep historical scores, can look back at history, and history is given uation scores after comparison.)
